Bruce Springsteen Performs After Cousin's Death

Three days after the sudden death of his cousin Lenny Sullivan, Bruce Springsteen showed a brave face and hit the stage in New York City.

"He's doing fine," said former Rage Against the Machine guitarist Tom Morello, who joined Springsteen and the E Street Band Thursday night for the Rock & Roll Hall of Fame Concert celebration at Madison Square Garden.

"I expressed my condolences. I know that he cancelled a show the other night, but tonight's show is very much a celebration of music and life," says Morello.

Sullivan, an assistant road manager for Springsteen's band for the past 10 years, was found dead Monday night at a Kansas City hotel. Police at the time said they did not consider the death suspicious. A message on Springsteen's Web site described Sullivan as "a warm and sensitive person [who] was beloved by Bruce, the Band, the crew, and the entire Thrill Hill family."

Yet the Boss kept to his Rock & Roll Hall of Fame commitment, performing a nearly two-hour set. He flashed smiles and shared moments of laughter as he sang "Pretty Woman" with John Fogerty and other tunes with Billy Joel, including "New York State of Mind."
